1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Geniculate axons are initially guided to discrete epithelial placodes in the lingual and palatal epithelium that subsequently differentiate into taste buds. In vivo approaches show that brain-derived neurotrophic factor (BDNF) mRNA is concentrated in these placodes, that BDNF is necessary for targeting taste afferents to these placodes, and that BDNF misexpression disrupts guidance. We used an in vitro approach to determine whether BDNF may act directly on geniculate axons as a trophic factor and as an attractant, and whether there is a critical period for responsiveness to BDNF. We show that BDNF promotes neurite outgrowth from geniculate ganglion explants dissected from embryonic day (E) 15, E18, infant, and adult rats cultured in collagen gels, and that there is a concentration optimum for neurite extension. Gradients of BDNF derived from slow-release beads caused the greatest bias in neurite outgrowth at E15, when axons approach the immature gustatory papillae. Further, neurites advanced faster toward the BDNF bead than away from it, even if the average amount of neurotrophic factor encountered was the same. We also found that neurites that contact BDNF beads did not advance beyond them. At E18, when axons would be penetrating pregustatory epithelium in vivo, BDNF continued to exert a tropic effect on geniculate neurites. However, at postnatal and adult stages, the influence of BDNF was predominantly trophic. Our data support a role for BDNF acting as an attractant for geniculate axons during a critical period that encompasses initial targeting but not at later stages.
